[0028] like Figure 1 As shown, the screen plate positioning assembly includes an upper positioning seat 2 and a lower positioning seat 3, which are arranged on the frame 1 one above and one below the other, and the screen plate is placed vertically between the upper positioning seat 2 and the lower positioning seat 3.

[0029] The first gluing mechanism is located on one of the left and right sides of the lower positioning seat 3 , and includes a first lifting seat 4 , a first striker 5 , a first lifting rod 6 , a first scraper 7 , a first elastic member 8 and a first driving member 9 .

[0030] The first lifting seat 4 can be slidably arranged on the frame 1 up and down, the first driving member 9 is connected to the first lifting seat 4, the first scraper 7 is an inclined scraper with one end high and the other end low, the high end of the first scraper 7 is movably connected to the first lifting seat 4, the low end of the first scraper 7 is a blade end that can flow out the photosensitive adhesive, and the blade end of the first scraper 7 faces the screen; the first striker 5 can be slidably arranged on the first lifting seat 4 left and right, and a first elastic member 8 is provided between the first striker 5 and the first lifting seat 4, and the first lifting rod 6 is fixedly arranged on the first striker 5 and supported below the first scraper 7.

[0031] The second gluing mechanism is located on the other side of the left and right sides of the lower positioning seat 3, and the second gluing mechanism includes a slide 11, a limit rod 12, a second lifting seat 13, a second collision rod 14, a second lifting rod 15, a second scraper 16, a second elastic member, a second driving member 17 and a third driving member 18.

[0032] The slide 11 can be slid left and right on the frame 1, and the second driving member 17 is connected to the slide 11. A push rod is provided on the side of the slide 11 close to the screen, which is used to push the screen so that the screen is respectively against the upper positioning seat 2 and the lower positioning seat 3.

[0033] The second lifting seat 13 can be slidably mounted on the slide 11 up and down, the third driving member 18 is connected to the second lifting seat 13, the second scraper 16 is an inclined scraper with one end high and the other end low, the high end of the second scraper 16 is movably connected to the second lifting seat 13, the low end of the second scraper 16 is a blade end that can flow out the photosensitive adhesive, and the blade end of the second scraper 16 faces the screen; the second striker 14 is slidably arranged on the second lifting seat 13 left and right, a second elastic member is provided between the second striker 14 and the second lifting seat 13, and the second lifting rod 15 is fixedly arranged on the second striker 14 and supported below the second scraper 16.

[0034] In specific settings, such as Figure 1 and Figure 2 As shown, the first gluing mechanism is located on the left, the second gluing mechanism is located on the right, and the first driving member 9, the second driving member 17 and the third driving member 18 are all cylinders.

[0035] A control box is provided on the left side of the frame 1, which integrates air pressure system components such as a pressure gauge and a pressure regulating valve. The pressure regulating valve is provided with an air inlet pipe and an air outlet pipe. The air inlet pipe is directly connected to the factory's air pump. There are two air outlet pipes, one of which is connected to the second drive member 17 for controlling the left and right movement of the slide 11, and the other is connected to the first drive member 9 and the third drive member 18 for controlling the synchronous up and down movement of the two lifting seats.

[0036] Of course, in addition to pneumatic drive, electric, hydraulic drive and other forms can also be used, and there is no restriction on this here.

[0037] The upper and lower positioning seats are used to position the screen. The lower positioning seat 3 is an L-shaped positioning seat with an opening that extends to the right. The limiting rod 12 is located on the L-shaped opening side of the lower positioning seat 3. When the limiting rod 12 moves leftward with the slide 11, the limiting rod 12 pushes the screen so that the lower end of the screen abuts against the lower positioning seat 3 and the upper end abuts against the upper positioning seat 2, thereby firmly limiting the screen.

[0038] like Figure 2 and Figure 3 The first scraper 7 and the second scraper 16 are both provided with a holding groove for holding the photosensitive adhesive. When the first scraper 7 and the second scraper 16 swing downward under the action of gravity, the photosensitive adhesive can flow out from the blade ends of the two scrapers.

[0039] The working process of this device is as follows:

[0040] 1. Positioning the screen

[0041] like Figure 1 and Figure 2As shown, the screen is placed vertically between the upper and lower positioning seats, and then the second driving member 17 is controlled to drive the slide 11 to move to the left. At this time, the limiting rod 12 will move to the left and push the screen to abut against the upper and lower positioning seats, thereby achieving a firm limit on the screen.

[0042] 2. Coating photosensitive adhesive

[0043] When the slide 11 moves to the left, the second impact rod 14 will also move with it. When the silk screen is positioned, the second impact rod 14 will collide with the first impact rod 5, and then the two impact rods will squeeze the elastic parts on the impact rods and retreat synchronously. When the two impact rods retreat, they will drive their respective lifting rods to retreat. When the lifting rods retreat, the two scrapers lose their support and will swing downward, causing their respective blade ends to move downward, and the photosensitive glue will flow out. The photosensitive glue will adhere to both sides of the silk screen.

[0044] Then, the first driving member 9 and the second driving member 17 are controlled to work, so that the first lifting seat 4 and the second lifting seat 13 move upward synchronously until they reach the top of the screen, thereby achieving gluing on both sides of the screen.

[0045] 3. Device reset

[0046] When the gluing of the silk screen is completed, the second driving member 17 is controlled to drive the slide 11 to move to the right and reset. At this time, the limit rod 12 no longer squeezes the silk screen, and the two impact rods will also separate and disconnect. The elastic member will drive each impact rod to reset. After the impact rod is reset, the ladder lifting rod will also reset and rest against the corresponding scraper again. The scraper will swing upward and the photosensitive glue will stop flowing out.

[0047] Finally, the first driving member 9 and the second driving member 17 are controlled to work, so that the first lifting seat 4 and the second lifting seat 13 are synchronously moved downward and reset, and the entire gluing process is completed.

[0048] In actual application, the end of the first impact rod 5 or the second impact rod 14 close to the screen can be shortened by a certain length compared to the corresponding end of the other impact rod, and then a gasket 10 can be removably set here. In this way, by setting gaskets 10 of different thicknesses, it can be used for gluing screens with different glue coating thicknesses.

[0049] To sum up, this device mainly simulates the arm lifting and gluing action during manual gluing by driving two lifting seats to lift and apply glue synchronously, thereby changing manual silk screen gluing to automatic silk screen gluing, thereby reducing manual labor intensity, reducing labor costs, improving gluing efficiency, and ensuring gluing quality.

[0050] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations to these embodiments without departing from the principles and purpose of the present invention are all within the scope of protection of the claims of the present invention.
